We offer a comprehensive range of fertility treatments and diagnostic tests, including the most advanced genetic testing methods available. Preimplantation genetic diagnosis, or PGD, in particular has become an invaluable adjunct to in vitro fertilization (IVF) in recent years, helping to promote higher success rates and more healthy pregnancies.

Our fertility specialists discuss preimplantation genetic diagnosis (PGD) benefits in detail during consultations at our Los Angeles, CA fertility clinic. Many patients, especially those who are carriers of certain genetic disorders, elect to include PGD as part of their IVF treatment for their own peace of mind.

Are you a good candidate for PGD as part of your fertility treatment? To find out, please schedule your initial consultation at Pacific Fertility Center today.

What Is PGD?

PGD is a diagnostic procedure used prior to embryo transfer to help identify genetic defects contained within embryos created during the IVF process. The goal of PGD is to detect specific genetic diseases through the examination of DNA in order to decrease the chances of those diseases being passed on to the child in the event of successful pregnancy. The embryos containing problematic genes are separated from those free from defects. A healthy embryo is then transferred to the uterus.

What Are the Benefits of PGD?

The primary benefit of PGD is that it lowers the risk of specific genetic diseases being passed on to children conceived via IVF. The procedure:

  • Can be used to identify more than 100 known genetic diseases and conditions.
  • Allows patients who are carriers of genetic disorders to attempt to conceive with a significantly reduced risk of passing those disorders on to their children.
  • Helps to prevent unhealthy embryos from being transferred to the uterus by identifying genetically flawed embryos, thus improving the odds of successful pregnancy.
  • Allows patients to reassess their decision to continue with their pregnancy, as implantation has not yet occurred at this point.

It is important to note that PGD is by no means a comprehensive test of all possible genetic diseases, and it does not entirely eliminate the risk of having a child with the known genetic disorders for which it tests. It is highly effective at reducing the risk of having such a child, but further testing during pregnancy may still be necessary.

Patients should also be prepared for the possibility that PGD could reveal that all of the embryos are genetically flawed, meaning that none of them can be transferred to the uterus.

In general, however, most patients who are good candidates for PGD find that the benefits outweigh the potential downsides.
